What orchestration solves
Building an agent by hand means juggling prompts, tool calls, retries, and state. An orchestration framework provides reusable structure so you describe the workflow instead of rewriting the plumbing each time.
Common building blocks
- Nodes or steps that each do one job, such as call a model or run a tool.
- Edges that route control based on the result of a step.
- Shared state that flows between steps and records progress.
- Hooks for logging, retries, and human approval.
Some frameworks model the flow as a graph; others use a linear chain or a set of cooperating agents.
Why use one
- Less boilerplate and fewer custom retry loops.
- Built in observability into each step.
- Easier to swap a model or tool without rewriting logic.
The risk
A framework imposes its own abstractions. If your task does not fit its shape, you fight the tool. Heavy frameworks also hide control flow, making bugs harder to trace. Many teams start with a thin loop and adopt a framework only when complexity demands it.
Key idea
Orchestration frameworks give agents reusable nodes edges and shared state so you describe a workflow instead of hand wiring plumbing, trading some control and transparency for less boilerplate and built in observability.
